Safety precautions to take if you smell gas
ß Turn off the gas emergency control valve immediately.
This is usually located near the gas meter.
ß Eliminate all sources of ignition in a safe manner.
Do not smoke, light cigarette lighters or matches.
ß Do not operate electrical lights or switches, i.e. do not switch them "On" or "Off".
ß Open all doors and windows to ventilate the area.
ß If the smell of gas persists, evacuate the building.
In the U.K you must now:
ß Call TRANSCO (Tel: 0 800 111 999)
ß Arrange for an appointment of a Corgi registered gas installer to visit the site
(Tel: Talking pages 0 800 600 900)
In other countries please follow relevant country specific procedures on gas.

Warning and Safety instructions
Building in
Fit wall units and cooker hood
before fitting the gas hob, to avoid
damaging the hob.
The room in which the gas hob is
~
installed must be at least 20 m
with a door or window in it which can
be opened to the outside air.
The veneer or laminate coatings of
~
worktops (or adjacent kitchen units)
must be treated with 100°C
heat-resistant adhesive which will not
dissolve or distort.
Any backmoulds must be of heat
resistant material.
Ideally the hobs should be installed
~
with plenty of space on either side.
There may be a wall at the rear and wall
or tall units at one side. On the other
side however, no unit or divider should
stand higher than the hob.
3
in size
recommended
Due to the heat radiated by the hob
and to allow cooking fumes to
dissipate it is essential that a
minimum safety distance a is
maintained between the worktop
cut-out and adjacent furniture, e.g. a
tall unit, as follows:
100 mm with KM 404 / 405
250 mm with KM 406
200 mm with KM 414 / 417
There must be a minimum safety
distance of 50 mm between the hob
and a back wall.
6
not recommended
not allowed
Warning and Safety instructions
An electric fryer must not be
~
installed next to a gas hob, as the gas
flames could ignite the fat in the fryer.
It is essential to maintain a distance of
at least 288 mm between these two
appliances.
These appliances must not be
~
installed over a dishwasher, washing
machine, tumble dryer, refrigerator or
freezer. The high temperatures radiated
by hobs could damage the appliance
below.
This equipment is not designed for
~
maritime use or for use in mobile
installations such as caravans, aircraft
etc. However it may be suitable for
such usage subject to a risk
assessment of the installation being
carried out by a suitably qualified
engineer.
Safety distance above appliances
b A minimum safety distance must be
maintained between the appliance
and a cooker hood above it. See the
cooker hood manufacturer's
operating and installation instructions
for details.
If the manufacturer's instructions are
not available for the cooker hood, a
minimum safety distance of at least
760 mm must be maintained. For any
flammable objects, e.g. utensil rails,
wall units etc. a minimum distance of
at least 760 mm must be maintained
between them and the hob below.
When two or more appliances are
installed together below a cooker
hood, e.g. a combiset and a gas
wok combiset, which have different
safety distances given in their
installation instructions you should
select the greater distance of the
two.
All dimensions in this instruction booklet
are given in mm.
Keep these instructions in a safe place
and pass them on to any future owner
of the appliance.

Important
General
Under no circumstances should
sealant find its way between the
frame of the top part of the hob and
the worktop.
This could cause difficulties if the
hob ever needs to be taken out for
servicing, (possibly leading to
damage to the frame and worktop).
The sealing strip under the edge of
the top part of the hob provides a
sufficient seal for the worktop.
21
Electrical connection
All electrical work should be carried
out by a suitably qualified and
competent person, in strict
accordance with current local and
national safety regulations (BS 7671
in the UK).
Connection should be made via a
suitable isolator or a double pole fused
spur connection unit which complies
with national and local safety
regulations and the on/off switch should
be easily accessible after the appliance
has been built in.
Installation, repairs and other work
by unqualified persons could be
dangerous. The manufacturer
cannot be held liable for
unauthorised work.
Ensure power is not supplied to the
appliance until after installation or
repair work has been carried out.
The appliance must only be
operated when built-in. This is to
ensure that all electrical parts are
shielded. Live parts must not be
exposed.
Do not connect the appliance to the
mains electricity supply by an
extension lead. These do not
guarantee the required safety of the
appliance.
Please make sure that the connection
data quoted on the data plate match
the household mains supply.
If the switch is not accessible after
installation (depending on country) an
additional means of disconnection must
be provided for all poles.
For extra safety it is advisable to install
a residual current device (RCD) with a
trip current of 30 mA.
When switched off there must be an
all-pole contact gap of 3 mm in the
isolator switch (including switch, fuses
and relays).
Important U.K.
This appliance is supplied for
connection to a single phase 230-240 V
50 Hz supply with a 3-core cable.
The wires in the mains lead are
coloured in accordance with the
following code:
Green/yellow = earth
Blue = neutral
Brown = live
WARNING
THIS APPLIANCE MUST BE
EARTHED
22
Important
The electrical safety of this appliance
can only be guaranteed when
continuity is complete between it and
an effective earthing system, which
complies with current local and national
safety regulations. It is most important
that this basic safety requirement is
present and regularly tested and where
there is any doubt, the electrical wiring
in the home should be tested by a
qualified electrician. The manufacturer
cannot be held liable for the
consequences of an inadequate
earthing system such as an electric
shock.
The manufacturer cannot be held
liable for damage which is the direct
or indirect result of incorrect
installation or connection.
Electrical connection
23
Gas connection
Connection to the gas supply, or
conversion from one type of gas to
another should only be undertaken
by an approved and registered gas
installer in strict accordance with
local and national safety and
building regulations, (e.g. Corgi
registered in the U.K.) Every
appliance should have its own
isolating valve and test point.
Check with your local gas supplier
about the type of gas and its
calorific value, and compare this
information with the type of gas
quoted on the hob data plate.
The installer is responsible for
ensuring that the appliance
functions correctly when installed.
Connection
Conversion to another type of gas is
described under the relevant Section.
The gas connection must be installed
so that connection can be made either
from inside or outside the kitchen unit,
and the isolating valve must be easily
accessible and visible (by opening one
of the kitchen unit doors, if necessary).
A test for possible leakages must be
carried out after installation.
Safety regulations demand that a
pressure test point is installed near a
gas hob to allow an engineer to test the
pressure, following servicing.
Depending on country, the hob is
supplied ready for connection to natural
gas or liquid gas (refer to label on the
appliance).
United Kingdom:
GB II 2 H 3+ 20 mbar, 28-30/37 mbar
Ireland:
IE II 2 H 3+ 20 mbar, 28-30/37 mbar
Depending on country a set of jets for
conversion to natural or liquid gas may
be included with the hob.
Please contact your dealer or agent for
the appropriate conversion jets if
necessary.

An appropriate rigid connection and

that it is not adversely heated when
the appliance is in operation.
In particular ensure that hot gas
exhaust cannot touch the gas pipe or
appliance connections.
After installing the appliance the gas
burners have to be set for local
conditions.
When the gas hob has been
installed it is essential to check that
neither the gas pipe nor the
electricity cable is in contact with hot
parts of the appliance or hot gas
exhaust, otherwise heat damage to
the pipe and cable could occur.

again using the spanner to
counterhold.
Changing the small jets
a Small jet with smaller jet diameter
(e.g. for liquid gas: 0.20).

(e.g. for liquid gas: 0.46).
^ Using a small screwdriver, unscrew
both small jets in the gas fitting.
